摘要： Disclosed herein are circuits and methods for a multi-electrode implantable stimulator device incorporating one decoupling capacitor in the current path established via at least one cathode electrode and at least one anode electrode. In one embodiment, the decoupling capacitor may be hard-wired to a dedicated anode on the device. The cathodes are selectively activatable via stimulation switches. In another embodiment, any of the electrodes on the devices can be selectively activatable as an anode or cathode. In this embodiment, the decoupling capacitor is placed into the current path via selectable anode and cathode stimulation switches. Regardless of the implementation, the techniques allow for the benefits of capacitive decoupling without the need to associate decoupling capacitors with every electrode on the multi-electrode device, which saves space in the body of the device. Although of particular benefit when applied to microstimulators, the disclosed technique can be used with space-saving benefits in any stimulator device.
摘要翻译：本文公开了用于在经由至少一个阴极电极和至少一个阳极电极建立的电流路径中并入一个去耦电容器的多电极可植入刺激器装置的电路和方法。在一个实施例中，去耦电容器可以硬连接到器件上的专用阳极。阴极可以通过刺激开关选择性地激活。在另一个实施例中，器件上的任何电极可以选择性地激活为阳极或阴极。在该实施例中，去耦电容通过可选择的阳极和阴极刺激开关放置在电流路径中。不管实施方案如何，这些技术允许电容去耦的优点，而不需要将去耦电容器与多电极器件上的每个电极相关联，这节省了器件体内的空间。虽然在应用于微型激励器时特别有益，但是所公开的技术可以在任何刺激器装置中具有节省空间的优点。

摘要： An improved implantable pulse generator (IPG) containing improved telemetry circuitry is disclosed. The IPG includes charging and telemetry coils within the IPG case, which increases their mutual inductance and potential to interfere with each other; particularly problematic is interference to the telemetry coil caused by the charging coil. To combat this, improved telemetry circuitry includes decoupling circuitry for decoupling the charging coil during periods of telemetry between the IPG and an external controller. Such decoupling circuitry can comprise use of pre-existing LSK circuitry during telemetry, or new discrete circuitry dedicated to decoupling. The decoupling circuitry is designed to prevent or at least reduce induced current flowing through the charging coil during data telemetry. The decoupling circuitry can be controlled by the microcontroller in the IPG, or can automatically decouple the charging coil at appropriate times to mitigate an induced current without instruction from the microcontroller.

Electrodes from either or both ICs can be chosen to provide stimulation, and one of the IC acts as the master while the other acts as the slave. Electrodes voltages on the slave IC are routed to the master IC, and thus the master IC can monitor both electrode voltages on the slave as well as electrode voltages on the master.

摘要： Sample and hold circuitry for monitoring electrodes and other voltages in an implantable neurostimulator is disclosed. The sample and hold circuitry in one embodiment contains multiplexers to selected appropriate voltages and to pass them to two storage capacitors during two different measurement phases. The capacitors are in a later stage serially connected to add the two voltages stored on the capacitors, and voltages present at the top and bottom of the serial connection are then input to a differential amplifier to compute their difference. The sample and hold circuitry is particularly useful in calculating the resistance between two electrodes, and is further particularly useful when resistance is measured using a biphasic pulse. The sample and hold circuitry is flexible, and can be used to measure other voltages of interest during biphasic or monophasic pulsing.

摘要： Combination charging and telemetry circuit for use within an implantable medical device uses a single coil for both charging and telemetry that is controlled via the use of an opto-switch. One or more capacitors are used to tune the coil to different frequencies for receiving power from an external device and for the telemetry of information to and from an external device. The opto-switch is coupled to the resonant circuit, but because its input is electrically decoupled from its output, it easy to control.

摘要： Communication and charging circuitry for an implantable medical device is described having a single coil for receiving charging energy and for data telemetry. The circuitry removes from the AC side of the circuit a tuning capacitor and switch traditionally used to tune the tank circuitry to different frequencies for telemetry and charging. As such, the tank circuitry is simplified and contains no switchable components. A switch is serially connected to the storage capacitor on the DC side of the circuit. During telemetry, the switch is opened, thus disconnecting the storage capacitor from the tank circuit, and alleviating concerns that this capacitor will couple to the tank circuit and interfere with telemetry operations. During charging, the switch is closed, which allows the storage capacitor to couple to the tank circuitry through the rectifier during some portions of the tank circuitry's resonance.
